鼠标事件在第一次计时器后不起作用 Tick [英] Mouse event don't work after first timer Tick

问题描述

我正在使用 powershell 开发一个带有图形界面的小工具，我对这个问题很着迷...

I'm using powershell to develop a little tool with graphic interface and I'm going crazy with this issue...

例如:我在表单上有一个标签，显示 ping 的实时"状态.同时，如果您单击标签，则会显示一条弹出消息.

For example: I have a label on a form that display "real-time" status of a ping. In the same time, if you click on the label, a popup message is displayed.

    function GoogleStatus ($Label)
    {
            $Google = "www.google.com"

            If (Test-Connection -ComputerName $Google -Count 1 -Quiet)
                    {Label.Text = "Yes"}
            else
                    {Label.Text = "No"}
    }

    function HelloMsg
    {
            [System.Windows.Forms.MessageBox]::Show("Hello","Funny Window",0,32)
    }


    [void] [Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms")  

    #Forms
    $Form = New-Object System.Windows.Forms.Form
    $Form.Size = '150, 220' 

    $Label = New-Object System.Windows.Forms.Label  
    $Form.Controls.Add($Label)
    $Label.Location = '10, 30'
    $Label.Size = '75, 20'
    $Label.Add_Click({HelloMsg})

    #Timer Init
    $Timer = New-Object 'System.Windows.Forms.Timer'
    $Timer.Interval = 3000
    Timer.Add_Tick({GoogleStatus $Label})
    $Timer.Enabled = $True

    #Show Interface
    $Form.ShowDialog() 

在计时器的前 3 秒内，单击标签正确显示弹出消息.但是如果我等了3秒以上，点击标签就没有效果了.

During the first 3 secondes of the timer, clicking on the label display correctly the popup message. But if I wait more than 3 seconds, clicking on the label has no effect.

请帮忙:(

推荐答案

测试连接的超时值必须小于您的计时器间隔.谢谢@Eric Walker https://stackoverflow.com/users/4270366/eric-walker

The timeout value for test-connection has to be less than your timer interval. Thank you @Eric Walker https://stackoverflow.com/users/4270366/eric-walker
